Dropzone library makes easier to implement file upload using drag and drop on the page.

After file uploading, it shows the preview of the file in the upload area.

All the thumbnails are removed when the webpage is get refreshed.

To recreate the thumbnails after page refresh needs to send AJAX request to get all files list for adding thumbnails while initializing Dropzone.

In this tutorial, I show how you can display existing files stored on the server in Dropzone file area with jQuery AJAX.

Dropzone is a JavaScript library which allows uploading file by drag’n’drop and display the file preview after upload.

It is easier to add to the page and it does not depend on any library like jQuery.

The file will upload to the server via AJAX.

AJAX pagination makes it easier to display the large list of records in multiple pages without refreshing the whole page when navigating.

While navigating pages if you refreshed the webpage then it will load record from 1st instead of page position before the refresh.

E.g. If you are on 5 page then it will again start from 1 when webpage reload.

To retain the position, I am using COOKIE to store the page number and use it after page successfully load to fetch records in CodeIgniter.

AJAX makes easier to perform operations without submitting the form like – fetch, insert, delete records from MySQL database, file uploading, etc.

Using AJAX in WordPress is a little different. Here, need to consider two things –

  • AJAX sent URL should be admin-ajax.php.
  • wp_ajax action hooks.
